STOVEPlPE-CLAMP.

SPECIFICATION forming part Of Letters Patent N0. 7 33,7 85, dated. J1113 14, 1903. Application filed February 24,1902. Serial No. 95,485.(No model.)

cured in position, which is adjustable to accommodate chimney-walls ofvarying thickness, which effectually prevents soot and smoke escapinginto the room, and which is of simple, strong, durable, and cheapconstruotion.

To this end the invention consists in certain novel and peculiarfeatures of construction and combinations of parts, as hereinafterdescribed and claimed, and in order that it may be fully understoodreference is to be had to the accompanying drawings, in which- Figure lis a vertical section of a portion of a chimney and of a pipe-clampembodying myinvention, the section being taken through the center of theclamp. Fig. 2 is a front view of the clamp and of the chimney-pipesection detached from the chimney. Fig. 3 is a detached plan view of thelocking-bar.

Referring to the drawings in detail, A designates a split clamp-band, ofspring metal, provided with substantially parallel ears connected by astove-bolt O, a perforated locking-bar D being secured on said boltbetween said ears and capable of vertical movement,

as indicated by dotted and full lines, Fig. 1, the perforations of saidbar being arranged in longitudinal series, so that their axes shallextend substantially vertical when the bar occupies its operative orsubstantially horizontal position, as hereinafter explained.

F is the chimney-section of the stovepipe, the same being fitted in thechimney-hole, as shown, and of length to project some distance into theroom from the chimney, the band A being clamped tightly on saidprojecting portion by bolt 0, with the band ears disposed verticallyabove the center of the pipe, the customary collar E fitting snugly uponthe projecting end of the pipe between the band.

and the inner face of the chimney. B designates a substantially U-shaped clamp-bar extending through the chimneyhole above the pipe andalso through the collar and between the ears of the band, one of thearms of said clamping-bar being disposed within the chimney flue orpassage and the other forward of the inner end of the pipe.

To secure this pipe-clamp in position, the clam p-bar is first rotatedso thatits arms shall be pendent to permit the'pipe-section, with theband and collar on its outer end, to be slipped into the chimney-holeuntil the rear arm of the clamp-bar is disposed within the chimney fiu'eor passage, and the collar is pressed by the clamp-band snugly upagainst the face of the chimney. The operator then with one hand causesthe perforated lockingbar to assume about the position shown in dottedlines, Fig. 1, and with the other rotates the clamp-bar until its armsproject vertically upward. He then draws said clamp-barforward until itsrear arm bears snugly against the front Wall of the chimney, as shown bydotted lines, Fig. 1, and while holding it in this position he lowersthe locking-bar and causes the engagement of one of its holes with theforward arm of the clamp-bar, and thereby clamps the pipe-sectionimmovably and reliably in the chimney. To remove the pipe-section forthe purpose of taking the stovepipe down, the locking-baris disengagedfrom the front arm of the clamp-bar. The latter is then pushed inwardslightly, so as to remove it from frictional contact with the wall ofthe chimney, and is turned downward until its rear arm lies whollywithin the plane of the chimney-hole. The entire device can then bewithdrawn from the hole.

From the above description it will be apparent that I have produced astovepipeclamp which embodies the features of advantage enumerated asdesirable in the statement of invention and which may obviously bemodified in some particulars withoutdepar'ting from its spirit and scopeor sacrificing any of its advantages.

Having thus described the invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A pipe-clamp, comprisingapipe-section,

ICO

a clamp-band thereon, a clamp-bar on the pipe and bearing a slidingrelation to the clamp-band, and a locking-bar carried by the clamp-bandtoengage the clamp-bar.

2. A pipe-clamp, comprisinga pipe-section, a clamp-band thereon, aclamp-bar also upon the pipe-section and provided with an arm adapted tooccupy the chimney flue or passage and to engage the front wall thereof,and a locking-bar carried by the clamp-band and engaging the clamp-barto hold its arm against the chimney.

3. A pipe-clamp, comprising a pipe-section, a clamp-band thereon, aclamp-bar also upon the pipe-section and provided with an arm adapted tooccupy the chimney flue or passage and to engage the front wall thereof,and a perforated locking-bar carried by the clamp-band and engaging theclamp-bar to hold its arm against the chimney.

4.. A pipe-clamp, com prising a pipe-section, a collar thereon, aclamp-band also thereon forward of the collar, a clamp-bar upon thepipe-section and provided with an arm adapted to be disposed Within theflue or chimneypassage, and having a sliding relation with theclamp-band, and a locking-bar carried by the clamp-band and adapted toengage and lock the clamp-bar against movement.

5. A pipe-clamp, comprisingapipe-section, a collar thereon, a clamp-bandalso thereon forward of the collar, :1, clamp-bar extending jnstment andprovided with an arm at its rear end, and a locking-bar carried by theclampband and adapted to engage and lock the clamp-bar in the desiredposition.

6. A pipe-clamp comprising a pipe-section, a collar thereon, aclamp-band also thereon forward of the collar, a clamp-bar extendinglongitudinally of and upon the pipe-section and through the collar andclamp-band and provided with an arm at each end, and adapted forrotatable and longitudinal adjustment, and a perforated locking-barcarried by the clamp-band to engage the front arm of the clamp-bar.

7. In a Stovepipe-fastener, the combination of a Stovepipe-sectionadapted to fit in the chimneyhole, a U-shaped clamp-bar adapted toextend through said chimney-hole and to have the inner end thereof restagainst the side of the chimney-flue, and a hinged lockingbar adapted tobe secured to the Stovepipe-section, said locking-bar being providedwith perforations to receive the outer end of said clamp-bar, by whichsaid stovepipe-scction may be secured in position.
